`louter: surfaces :of Athe Walls a. aind turned in for engagement by an elementof the machine used to manufacture the paper box as is usual in connection with the turn-in now in use. No element ot' the machine is illustrated as it ormsfno part oi the pr-esentinvention, the form according to the present invention being applicable with any ot the known types of machines. Secured to the plate c as by screws cg are the transverse frame elements or bars d. Only two such transverse elements are illustrated in the drawings but it will be apparent that any number of such elements may be used dependent upon the size of the turn-in, it being evident that from manufacturing considerations a more rugged construction will be desirable for "turn-ins7 used-in the manufacture of boxes ot the size ot' hat boxes, for instance, than will be desirable in turn-ins7 used in relatively smaller boxes such as candy boxes, for instance, while the same considerations enter into the construction of adjustable forms used in the manufacture oit still smaller boxes such as pill boxes, i'or instance. The paper engaging elements proper of the form are supported upon what may be termed an interior frame which includes the transverse supporting members or bars (Z and longitudinally extending side frame menibers f. These 'form elements proper comprise L-shaped members or corner pieces c which are provided in the longer leg of the L with holes e', ln" to be engaged by screws e2 movable in slots formed in longitudinal side frame members f. The side members are provided with a plurality of the slots f, F each of which corresponds with one ot the holes e', for a purpose which will hereinafter appear. One modification of the means 'for adjusting the size of the turnin has been illustrated in the lett of Figure l while another modiiied construction is shown at the right of that figure.

Reference will First be had to the construction disclosed at the lett of Figure l. Between the slots f and F the side frame members f are secured respectively to the turned over ends g ot transverse slides g as by means of VrivetsVf/LX. Each ot ,the slides g is provided with a longitudinally extending slot g2 and the slides secured 'to the respective side frame members are disposed upon opposite sides or" the transverse element d which is provided centrally thereof with a hole d through which a bolt Z2 passes to engage by means of its head d and nut d* the outer marginal surfaces of the respective slides g. By loosening up on the nut d4 the two slides g may be drawn in opposite directions with respect to the transverse element al, the slots g2 permitting such transverse movement, and a'iter the desired width of the form is obtained the `nut may be tightened to rigidly maintain the form at the desired width. It will be apparent that when the corner member c is at its extreme inner position the screw e2 is at the inner end of one slot f but that when the corner e is moved towards its extended position with respect to the longitudinal side member f the said hole c will move out et register with the slot opposite that portion of the side frame member to which the slide g is secured. In consequence a second hole E is provided which in this situation will be in register with the second slot F for the reception et the screw e2, the screw sliding then in the slot F. It will be apparent that a single slot cannot be provided tor the reception of the screw in view of the 'tact that a certain portionof the wall is necessary for connection with the slide g. Between the inner ends of the corners e there will naturally be a space dependent upon the overall length of the 'form and it is proposed to provide a spacing member, which may be termed a lilling-in piece, /L of the same transverse diameter as the arms ort the Ls e whereby a continuous outer surface of the turn-in is aiiorded. A hole L is provided centrally of the member It and a co-operating hole f2 is also formed in the longitudinal element f so that a screw h2 carried in the hole may engage the hole it and rigidly secure the elements L, f in assembled relation. As the Ls e move away from each other, of course, the space between their inner ends will vary and therefore it is proposed to provide a plurality of iilling-in pieces /1r of different lengths in order to close the gaps between the end ot the Ls in their various positions of adjustment. The other leg es of theL is also provided with a threaded hole et for the reception ot a screw e5 slidable in one of a pair of slots z' in a spacing member e", each of the slots ot' the pair being designed to receive one oi' the screws (e5 and E5 respectively) threaded into the respective legs e3 of the corners. Between the legs c3 are also provided suitable spacing elements L in the same manner as hereinbeftore described in connection with the sides of the form, the screws 71,2 in this instance passing through an appropriate aperture in a guide j extending transversely of the form throughout approximately the entire width thereof and secured in any convenient manner to one ot the Ls as by the rivet y'2. The guide '7' is formed at its outer end with a slot 7'3 to permit unformi in the desiredsize, A spacing element h ot thel proper length to lit between tlieL re' is then introduced therebetween and tastenedin place by the screw le? increasing the length of t-he form to its more extended positions. The screws c2 may be removed trom the holes c and inserted; in the holes E through the slots F. To alter the Width ot the tornitlie iiut dit is loosened oiithe bolt da andy the screivs er", E are loosened whereafteil the sides may be drairn outwardly to contorni to the desired Width, the screws ci', E5 sliding inthe respective slots z' and ja. Then the desired width of the form is obtained `the screws et, E5 may be tiglgitened as 1:fell as the nut on the bolt (Z2 Whcreaiter i a proper spacer member VIt may be inserted and secured thereinby the screw al manner hereinbetore described in order to niaintainthe various component elements ot' they 'torni in rigid rela-tion and` to serve as a guide during the adjustinent lci the saine. the upper edge ot the longitudinal. sideineinbcis f" and thetransverse guiding elements a" are turned over to torni what may be called the toes f3 and 2, respectively which engage the upper edge of the legs ot the corners in a manner which will bei clearlyapparent jupon: inspection ot the drawings.. g v

The iiiodiiied means 'for pern'iitting variations in the size-y of the cturn-in as illustrated at the right hand side ot Figures l and 2 embodies the same-principle ot operation as that previously described, but involves a rearrangement ot parts tending toward simplilication in construction and manipulation. The slides G, G, are, as before, turned over at one end as at G and are secured at opposite ends respectively to the side frame members f between the slots f and F. In contradistinction to the construction previously described, however, these slides are disposed adjacent one another upon the same size of the transverse trame member CZ and are maintained in sliding relation tlienevvitli by a guide 7c ot inverted L-shape in cross section, the hoi"- Zontal leg c of the L extending over the top ot the slides and transverse frame member to seat in a cutout portion c4 ot the pla-te and be rigidly clamped therein by the screiv's G3'. The guide not only serves to guide the slides G in a 'transverse direction but the leg 7c serves to prevent angular displacement of the slides with respect to each other. The slides G are providedfwithslots (not shown) as before through Which passes a screw Z threaded into a hole d in the transverse member and serving not only to limit the extension ot the slides througl'i the instrumentality of the slots but also by means oft the head Z securing the guide, slides and transverse trame member together in the desired relation. Still referring to the-modified `construction illustrated at the right of Figures 1 and 2 .itwill be observedthat a guide mf Ais secured by mea-ns ci: the

' screws m to the transverse leg of one. of' the corner pieces c and @verlies Jfory a considerable distance Vthe proximate leg. of ydie adjacent corner piece. rlhe guide is lslotted as at m2 for sliding engagement with the screw 71,2 and is formed with an toe in. to ensure rectilinear movement oil the respective leO's ot the corner iieces. i3" co-oceratinf` La *i i :a

guide similar to that illustrated at the lett-hand side ot' Figures and 9, secured as before to the leg of the second corner` piece to overlie the guide iiin and slide- `with respect thereto, when the Width ot' the torni is varied, by means of thev slot j lfo'rmed therein, the screiv /LZ serving to secure 'the parts in the desired relation.

it will be apparent that thc coi'istructioii last described is somewhat simpler ot inanipulatioii than the construction lirst discussed since only two screws Z and lz need be manipulated in order to e'liect a change in the Width oi theform.

ift Will thus be seen that a simple and effective forni has .geen provided which is adjustable Within prescribed' limits whereby the necessity oit providing a plurality of separate unadjustable forms is cbviated and. i oiisiileraiiilc time, expense `and labor is saved.
